Subject [jira] [Commented] (HDFS-13856) RBF: RouterAdmin should support dfsrouteradmin -refresh command

Íñigo Goiri commented on HDFS-13856:
------------------------------------

I wasn't familiar with generic refresh and I had to go over the Namenode implementation to
get the idea so I may not be the best one to review this.
The code itself looks good and the implementation matches the NN one.

> Like namenode router should support refresh policy individually. For example, we have
implemented simple password authentication per rpc connection. The password dict can be refreshed
by generic refresh policy. We also want to support this in RouterAdminServer.
